ABSTRACT:
An extruding method for manufacturing an elongate strip partially having at least one cross-sectional T-shaped part composed of a head section and a leg section, which comprises extruding a material, partitioning the head section and the leg section in the vicinity of the exit end of the die, uniting the head section and the leg section naturally and solidifying the extruded strip. Hereby, recesses undesirably formed on the surface corresponding to the junction of the head section and the leg section composing the cross-sectional T-shaped part of the elongate strip when using methods heretofore known, can be prevented.
